The Panasonic DMC-GH4, also known as the “GH4K” for its ability to record 4K video, is available for pre-order at B&H for $1,700. UPDATE: And now Amazon as well.
The YAGH breakout box is $2,000. UPDATE: Also at Amazon.
A bundle of the two is $3,300, which saves you $400.
I ordered the body only. The price for the breakout box is reasonable, but what I love about this camera is that it obeys Wingrove’s Law.
The camera is said to ship in late April, the YAGH in late June, the bundle in late May.
